A sample of 8,000 subjects to represent the population of Finland aged 30 years and over was used to identify patients with severe dementia; 141 cases were found. The prevalence of all types of severe dementia was 1.8% in the whole study population and 6.7% in the population aged 65 years and over. The prevalence increased with advancing age to 17.3% in the age group 85 years and over. Primary degenerative dementia constituted 50% of all cases; multi-infarct and combined dementia, 39%; and secondary dementia, 11%. Fifty-seven percent of the patients lived in institutions.
